... invent: Electromagnets can take care of business
Engineers can find out how to improve upon a good idea using experiments. Now we must consider what can be changed on the electromagnet and try out the various possibilities.
 |
Change the lengths of the wires and the size of the iron core and count how many paper clips can be held. Make a table and write down your results. |
 |
Work together with each other. Teamwork has many advantages here. What can be learned from this experiment. Discuss with the others what is important for constructing a magnet. What does the strongest electromagnet look like? Using the available materials, construct the strongest electromagnet, count how many paper clips this supermagnet can hold, and send us a photo. |

 ...invent: Group crane with an electromagnet Teamwork is needed for this crane. A nice crane for exciting group competitions. The original idea is attributed to the educator Friedrich Wilhelm August Fröbel (1782-1852). |
 |
Here a group attempts to collect from the floor and place back in the box 10 scattered paper clips as quickly as possible. |
 |
The electromagnet is remote controlled. |
 |
Your electro-crane Construct a crane. Suspend an electromagnet on the crane's arm. Now you can collect and transport iron objects by remote control. Invent a tricky game or task for other kids. |
 |
Here are several ideas on how you can make the connections. |
 |
For what can you use the back and forth movement shown in the film? |
